Billy Clyde Gillispie , also known by his initials BCG, is a men's basketball coach, most recently at the University of Kentucky. His last name is spelled unconventionally, and is pronounced "Guh-LISS-pee".

After leading both UTEP and Texas A&M to postseason appearances one year after poor seasons, Gillispie became the only college basketball coach to be in charge of the NCAA program with the biggest turnaround in two consecutive seasons. Gillispie is known as an excellent recruiter who has managed to put together four straight top-25 recruiting classes. In his three seasons at A&M, the Aggies achieved three consecutive 20-win seasons for the first time ever.
